Oh yeah, Tiziana makes Su-Na look small, heck she makes most of the cast look small, save perhaps for Cassandra who's a literal goddess on Earth. Tiziana bashfully admits to being an F-cup, though there's no way to be sure at this time. Maybe, just maybe, if there's a third season of Freezing, we'll find out for sure. Though I'm not holding my breath on that one.
I want to know her sizes sorry for being a pervert but half of Freezing especially the readers most of the male audience looks at their bust because every time they fight they have a serious waldrove Malfunction and Tiziana is probably the hottest Pandora in the series she might have one of the largest busts in the series and then there is her age.
